Description
Technical Field
The utility model relates to a casting field, in particular to end cover foundry goods kidney-shaped groove oil pocket base psammitolite core box for mixer plunger pump.
Background
The casting is a technological process of smelting metal into liquid meeting certain requirements, pouring the liquid into a casting mold, cooling, solidifying and cleaning to obtain a casting with a preset shape, size and performance. Casting is one of the fundamental processes in the modern device manufacturing industry, because of the near shaping, the cast blank achieves the purpose of no machining or little machining, which reduces cost and manufacturing time to a certain extent.
At present, casting technology is often used for the end cover of the plunger pump of the stirrer. In the process of casting the end cover casting, the end cover casting needs to be matched through a casting mold and a sand core arranged in the casting mold, and for the sand core structure of the end cover, due to the particularity of some end cover structures, a mode of combining two sand cores together is often needed to form a cavity of the inner wall of the end cover.
When the two sand cores are combined, an assembly hole needs to be designed in one sand core, an assembly protrusion embedded into the assembly hole is designed in the other sand core, and when the two sand cores are combined, the assembly protrusion is embedded into the assembly hole and then the joint of the assembly protrusion and the assembly hole is fixed through glue joint. In the structure, when the sand core is molded, the core box structure is used, the core box structure comprises two split core boxes and a loose piece arranged in the core box, and the loose piece can move. When the core box is used for preparing the assembly hole on the sand core, the loose piece is inserted from the upper part of the core box, meanwhile, a groove for inserting the loose piece is formed in the upper end of the core box, and a bulge corresponding to the shape of the assembly hole is formed in the bottom end of the loose piece. When the loose piece is manually taken out from the upper part by adopting the structure, the shape deformation and the size fluctuation of the assembly hole are easily caused, so that the manufactured sand core does not meet the product requirement, and the size of the assembly hole is smaller, so that the deformation phenomenon is more easily caused.
